Rhubarb Dump Cake

READY IN: 1hr 5mins
Recipe by Sunshine

This recipe is wonderful. Very fast and easy to mix up can also use frozen rhubarb. Serve it nice and warm with some ice-cream or cool whip. The marshmallows give the cake a nice golden brown. Preparation time does not include time to clean and dice rhubarb. I put 12 for serving size according to the box, but I am sure you can get more out of a 9x13 inch pan. The recipe is sweet so a smaller piece may be better. Enjoy!

This was excellent and quick to whip up with some rhubarb I needed to use up. I told my mom about it and she said she had the recipe and it was called "My Man's Rhubarb Cake"
